Building permits, zoning and land rules in Worcester County, Maryland

Unincorporated Worcester County requires a building permit for building construction, including homes and additions; accessory structures 500 square feet or less and uses of land are excluded, though zoning approval may still apply¹. Worcester County uses the 2021 IBC, IRC and IECC with local amendments for building-permit submittals on or after May 29, 2024⁹. A landowner building directly and solely for personal use can bypass Maryland’s home-builder registration-number and Guaranty Fund-fee prerequisites by signing the required affirmation; the exception does not remove Worcester County’s building-permit requirement^1,4. An owner performing a home improvement also qualifies for Maryland’s contractor-license-number exception for that permit¹⁰. Inside Berlin, the town reviews building work and requires written building permits or approvals before work begins¹¹. Septic permitting remains with Worcester County Environmental Programs countywide³.

Worcester County Development Review & Permitting handles building construction, site plans and subdivisions; reach the department at (410) 632-1200 or 1 W. Market St. Room 1201, Snow Hill, MD 21863¹². A residential building permit needs three sets of construction drawings and three site-plan copies; commercial projects need four sets of architect-sealed drawings¹. Under the FY26 fee schedule, one- and two-family building work starts at $50 plus a square-footage/value formula, manufactured and mobile homes carry a $100 flat fee, and building reinspections cost $50 per occurrence¹³. Development Review & Permitting reviews site-plan information for zoning and code compliance before directing applicants to Environmental Programs¹. Occupancy or a change in land use requires a county zoning/occupancy certificate¹⁴.

Worcester County zoning applies to unincorporated land; use the county GIS zoning map and current code to identify the parcel’s district^2,15. Ocean City, Berlin, Pocomoke City and Snow Hill administer their own zoning^16,17,18,19. Septic permitting stays with Worcester County Environmental Programs countywide³. An ordinary dwelling in unincorporated Worcester County needs at least 500 square feet of livable gross floor area²⁰. Lot area, setbacks and height depend on the district and use; the private-well/private-septic provision sets a 100-foot minimum lot width²¹. Agricultural activities and agricultural-purpose-only subdivisions are exempt from Forest Conservation Law, while farm structures other than dwellings are exempt from district height limits except in AP; these are not blanket building-permit or zoning exemptions²².

The Worcester County Department of Environmental Programs reviews, permits and inspects septic systems countywide under delegated Maryland authority³. A qualified private-sector designer must prepare the plans; Environmental Programs must approve them, and the septic permit must be issued before building-permit signoff³. No part of an on-site system may be covered or used until the approving authority or its approved third party has inspected and approved it²³. Federal soil data rates 0% of Worcester County soils as free of severe limits for a conventional drain field, so budget for a site evaluation and potentially an engineered system²⁴. Property outside public water and sewer service needs a soil evaluation before construction of a plumbed structure²⁵. Within a sanitary service area, building and occupancy permits depend on the required public facilities reaching the county's specified completion milestones²⁶. Start with Environmental Programs²⁷.

Worcester County allows private, noncommercial seasonal camping in cabins, tents, RVs and manufactured or mobile homes in A-1 and A-2, but prohibits permanent or year-round occupancy under those provisions⁵. In A-1, each listed unit requires five acres, with no more than five units, a 400-foot minimum lot width and 100-foot front, side and rear setbacks; Department of the Environment approval also applies⁵. Ask the Zoning Division for A-2’s complete parcel-specific standards^6,28. Maryland adopts IRC Appendix AQ Tiny Houses, but the code framework does not authorize placement or occupancy on a particular Worcester County parcel²⁹. An ordinary dwelling in unincorporated Worcester County still needs 500 square feet of livable gross floor area and a zoning/occupancy certificate before occupancy^2,14. A qualifying manufactured home in A-1 needs a building permit, water and wastewater compliance, at least 1,000 square feet of floor area and a 20-foot minimum depth⁵.

1. Confirm the parcel's zoning district, allowed use and dimensional standards with the Zoning Division^15,28.
2. If public water and sewer are unavailable, obtain the required soil evaluation from Environmental Programs²⁵.
3. Have a qualified private-sector designer submit septic plans; the septic permit must precede building-permit signoff³.
4. For a private well, obtain Maryland's required well-construction permit⁸.
5. Submit the building application with three residential drawing sets and three site-plan copies, or four architect-sealed commercial sets¹.
6. Obtain a floodplain development permit for construction, alterations or additions in a special flood hazard zone^9,30.
7. Schedule county building inspections with 24 to 48 hours' notice and county septic inspection before the system is covered or used^3,23,31.
8. Do not occupy the building or change the land use until Development Review & Permitting issues the zoning/occupancy certificate¹⁴.

Before buying unincorporated Worcester County land, confirm the zoning district and applicable lot, setback and height standards with the Zoning Division^15,21,28. Check public sanitary-service requirements and flood exposure: sanitary-service-area permits depend on facility completion, while special-flood-hazard-zone construction needs a county permit and Coastal A and V-zone designs need professional certification^26,30. A driveway within state right-of-way needs an MDOT SHA permit³². County access-spacing rules govern specified development approvals; the commercial interparcel-connector requirement does not establish a universal residential-driveway rule^33,34. All rentals in unincorporated Worcester County need a rental license; short-term licenses cost $200 per dwelling unit annually and are subject to room tax³⁵. Short-term rentals require two off-street spaces, or three when the dwelling’s building permit was submitted on or after April 17, 2026; events for non-lodgers are prohibited³⁵.
